Abstract

The cyanate ester polymer, CTD 403, is being considered for use as an insulation material in future fusion devices. In this study, the moisture resistance of neat polymer, glass fiber/CTD 403 and copper foil/CTD 403 was studied. The results show that while prolonged exposure to moisture cause property degradation, however, most of the property loss is recovered after drying the specimens.
